Study Associates IQ with Breastfeeding Duration

May 09, 2002

Significantly higher scores on verbal, performance, and full scale WAIS IQs were observed relative to increased duration of breastfeeding in two independent samples of young adults, assessed with two different intelligence tests, according to a study published in JAMA, the Journal of the American Medical Association.

The research, funded primarily by the National Institutes of Health, was conducted in a sample of 973 men and women, and a sample of 2,280 Danish military men, all born in Copenhagen, Denmark, between October 1959 and December 1961.

June Machover Reinisch of the Kinsey Institute for Research in Sex, Gender and Reproduction says, “We are really quite certain that what we are seeing here is the effect of the duration of breast-feeding on an individual’s intelligence.”
